CLOCK-MOVEMENT FRAME.

forming part of Letters Patent No. 352,715, dated November 16,1886.

Serial No. 205,791. (No model.)

To all whom it may concern:

Be it known that l, SWEN P. SANDMARK, of lshpeniing, in the county of Marquette and State of Michigan, have invented a new and Improved Clock-Movement Frame, of which the following is a specification, reference being had to the annexed drawings, forming a part thereof, in which- Figure 1 is a front elevation of my improved clock-movement frame, with a portion thereof removed. Fig. 2 is a detail view of the removed portion of the frame. Fig. 3 is a side elevation of the frame and Fig. 4c is a transverse section taken on line :0 x in Fig. 1.

Similar letters of reference indicate corresponding parts in the different figures of the drawings.

The object of my invention is to provide a clock-movement frame, which will permit of removing either of the spring-arbors with their springs without disturbing the other portion of the movement, or removing all the gearing of either side without disturbing the central portion of the movement.

My invention consists of the construction and arrangement of parts, as will be hereinafter fully described, and specifically pointed out in the claim.

The back plate, A, is of the usual descrip' tion, and is apertured to receive the pivots of the various arbors of the movement. The front plate, B, is divided into five pieces-the central part, 0, which is supported by studs a I) from the back plate in the usual way, the lateral parts D D,supported by studs 0 c from the back plate,and the lateral parts E E, sup ported by studs d d from the back plate and by screws'e c, passing through the inner ends of the parts E E into the oentralpart, O, and the lateral parts D D. The parts E E are provided with apertures f, for receiving the outer ends of the spring-arbors. The parts E E are offset, so that the portions which overlap the central part, 0, and the lateral parts D D may be secured by the screws 6 c, in the manner described, with the body of the parts E E lying in the same plane as the other portions of the front plate, B.

WVhenit is desired to remove the springarbor and spring of the striking or time side of the movement, the screws 0 e are loosened, the nut on the stud d or d is loosened, when the part E or E of the plate may be readily removed, permitting of taking out the springarbor and spring without disturbing other parts of the clock-movement.

To remove all the gearing of one side of the movement, the plates D E or D E will be removed together, allowing the screw 6, which clamps the parts I) E together. to remain in, and removing the nut from the studs 0 c.

When it is desired to remove the front plate entire,the screws 6 6 will not be loosened, but the entire plate will be taken olf after removing the nuts from the studs c c c d d and taking the pin out or" the stud b.

I do not limit or confine my improvement to any particular form of clock movement frame, nor to any particular way of dividing the frame, as these may be varied according to circumstances.

It is obvious that my improvement may be applied to the back plate of the frame, instead of the front, if desirable.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, ist A clock-movement frame formed of the back plate, A, the central platesection, C, supported from the back plate, and the lateral plate-sections D DE E,secured to each other and to the central section, 0, and supported from the back plate by studs, substantially as shown and described.
